, forming part of the managers instrument,

together with the circuits and connections therefor, are all illustratedbeneath the dotand-dash line A A. Above the dot-and-dash line A. areindicated three branch lines, which Y correspond to separatestenographers instruinents.

The stenographer s instrument includes an acousticon transmitter 10,adapted to receive spoken sounds at any reasonable distance therefrom,and an ordinary telephone-receiver 11. 12 indicates an ordinarytelephone-hook by which the receiver is hung up, and 13 indicates theusual callbells. l4 denotes a push-button or switch convenientlydisposed at each stenographers instrument.

For the puipose of supplying the necessary electric current, a number ofbatteries 15, 16, and 17 may be used, and which are convenientlysituated at the managers end of the line, about or within his desk orabout his ofiice. As will be seen from the diagram of circuits in Fig.1, each annunciator-drop 6 is adapted to close a special circuit at thepoints 18 whenever an annunciator-drop falls to expose the numberbeneath. In practice this connection is made by a lever or blade at thepoint 19, Fig. 2, although the alsoexerts a sli tion to throw t e loud.earpiece into circuit.

Referring now again to Fig. 1, we will describe the various conditionsand operations which take place and the electrical circuits which arecompleted in the normal operation of the apparatus. The diagram ofcircuits shows the apparatus in its normal or passive condition when noone is talking. We will suppose the manager wishes to dictate a letterto the stenographer at station No. 3. Under these circumstances he takesthe plug 7 and inserts it in the aperture 7 of station No. 3. He thenpresses the push-button 8, completing the following circuits: frombattery 15 at station No. 3 downward'through wire m, spring-contacts mwith the wires m m, push-button 8, (depressed as above described, wire mconnection m,.contact m wire on, stenog'ra hers call-bell 13, hook 12,wire m", back to attery. Thus the call-ballot Sta tion No. 3 rings,and'the stenographer takes her receiver oif the hook and presses thebutton 14. This completes the following circuit: from button 14, throughwire 72/, battery 17, wire 12?, annunciator 6, which is the third one onthe managers instrument, causes it to drop into the dotted positionshown, wires n and a, back to the pushbutton 14. In this way the managerlearns that stenographer at station No. 3 has correctly received hissignal and is ready "to take his dictation. He accordingly preandwithout any necessity close to the transmitter. This is on account ofthe fact that an acousticon-transmitter is used, so that the manager maydictate at his desk or in any convenient manner, exactly as suits hishabit of dictation when a stenographer is present in the room. Thetalkingcircuit under these circumstances is completed as follows: fromacousticon-transmitter 2 through Wires 0 0 contact 0 wire n battery 17,wire n, contact 0*, (nowcompleted,) stenographers receiver 11, wire mcontact m and wire m back to the acousticon transmitter 2. This istherefore a closed circuit, including the transmitteij-a battery, andthe stenographers receiver, as required. The dictation proceeds in theusual way, and under these circumstances the stenographer willirequently desire to ask about the nature or spelling of a word or nameor ask to have a sentence repeated or further data given, and underthese circumstances it is merely necessary for her to remark the factsin an ordinary tone Without I placing her lips to the transmitter orinany way removing her attentionfrom the note 'book before her. Thes'tenographers remark is received n the acoust1con-transceeds with thedictation in an ordinary voice of placing his lips loud earpiece at themanagers scares mitter 10 ather stat-ion and is received in theinstrument by an entirely separate circuit from the managerstalking-circuit. This circuit is as follows: from the stenographersacousticontransmitter 10, through hook 12, wire m battery 15, wire m,connection of, and wires m and m switch-blade 23, wire loud earpiece 3,wires p p and 7), connection p, Wire a, connection p, back to theacousticontransmitter 10. It will be observed that in this circuit aseparate set of line-wires are traversed than in the case of themanagers talking-circuit. In this way there is no interterence of themessages and no contusion. It will also be seen that the managerstalking-circuit does not include his own receiver,

nor does the stenographers talking-circuit 5 include her receiver. Thisalso obviates the confusion which would otherwise occur on account ofthe loud transmitters and loud earpieces, which are of course anessential with a dictograph.

While the instrument is articularly designed for the purpose of ictatingto the corps of stenographers, it is also adapted for communication withvarious heads of departments about the building in the same way as anordinary telephone. In this case, however, the convenience is promotedby the loud-speaking and bud-receiving features. In some cases, however,it may be undesirable to have the reports of the various oilicers in thebuilding received at the loud earpiece in the managers ollice. This isparticularly the case when outsiders happen-to be present therein. Underthese circumstances the manager takes the receiver 4 oil its hook andpresses the switch-lever 21. This moves the blade 23 away from plate 25and into contact with spring-plate 24. As will be clear from Fig. 1,this has the ei'l'ect of cutting the loud earpiece 3 out of circuit andcutting the ordinary receiver 4 into circuit. Thus the manager is ableto receive messages by the loud earpiece or the ordi-' nary receiver atwill, according to which hap pens to be desirable.

An additional feature of our apparatus relates to the means by which thestenographer at any station or a foreman or superintendent of anydepartment may call up the central manager. It frequently happens thatthe manager calls up some one in the manner above described, but theparty is temporarily absent. It is therefore desirable to have theapparatus arranged so that the manager may o on about his business orother matters and e notified-When the absent party returns. Thereforewhen the manager calls up .a party and finds him absent he moves overthe switch-lever 9 on his instrument and then goes on With his otherbusiness. When the absent party returns and presses the button 14, whichdrops the corresponding annunciator for the station called. thenresponds and completes his conversation.

In this way the managccs call-bell 9 is rungin addition to the drop of the annun- The manager tion in the usual way.It will be observed that the above callizg-circuit from the receiving orstcnographens stations to the managers station is wholly independent ofwhether or not the mama-gens jack is in posi- It is therefore possiblefor the managcr to be dictating to another stenographer when the call isreceived from the returned absent party, which fact is indicated by thedrop of the appropriate annunciator and the ringing ol the manager bell,if desired. The manager then plugs in his jack to complete thetalking-circuits. In like manner the manager may always be called by anyparty about the building; but such party cannot break into the managersconversation until he is ready,'which fact is announced by his pluggingin the proper" jack and pressing the button 8.

A feature of the invention relates to the recording of conversatio;iswhich occur in the managers ollice. hen this is desired, the managerplugs in. a stenographer who has been instructed to take down suchconversation, and thereupon she hears and records all of theconversation which occurs in the managers oilicc. This is frequentlyadvantageous for the purposes ol" evidence, &c.

As for the particular instruments employed we have found extrentelysuccessful in practice the acoust-icon-transmitter described ir. LettersPatent No. 711,974.

The receiver at the managers station may embody the same principles inthe construction ol" diaphragm, having of course the switch mechanismillustrated in Figs. .3, 4, and The loud earpiece 3 is conveniently'made by forming a protuberance or boss 31 upon an ordinary or the abovetype of receiver and fitting upon this a born or reinforcing-cup 32. Theinstrument is of course wound and adjusted to give a loud-speakingquality. 4

The construction of the annunciators 6 and the jacks 7 7 may be of anyordinary or approved construction.
